GAS-PRODUCER APPARATUS.

SPECIFICATION forming part of Letters Patent No. 795,258, dated July 18, 1905. Application filed February 6, 1905- Serial No. 244,501.

To all whom it may concern;

Be it known that I, OARLETON ELLIs, a citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Gas-Producer Ap paratus, of which the following is a specification.

My invention relates to internal-explosion engines in which producer-gas is used as a source of power.

My invention relates particularly to apparatus so designed that the troubles from premature ignition and explosion, d ue principally to hydrogen in the gas applied to the engine, are avoided. My apparatus is also so designed as to secure great economy in the production of the gas and economy in its utilization.

In order to eliminate hydrogen from the gas supplied to the engine, I have to eliminate steam from the producer, and to create the necessary endothermic reaction in the producer that maintains its temperature at the proper degree I make use of carbon dioxid, taken, preferably, from the products of com bustion, as the cooling agent in lieu of steam. By the explosion of the producer-gas in the engine carbon dioxid is produced in such amount that, provided a portion of the sensible heat be abstracted from these products of explosion prior to their entrance into the producer, a satisfactory endothermic cooling of the producer is secured and a control of the temperature is made possible without the use of so objectionable a medium of control as steam.

My invention comprises a gas-engine, a gasproducer, and a cooling device, together with suitable connections and valves for adjustment of the flow of the various gases employed.

In the accompanying diagrammatic drawings, Figure 1 represents an elevation of the assembled apparatus, and Fig. 2 shows one of its practical applications as applied to the propulsion of vessels.

Referring to Fig. 1, the gas-producer is shown diagrammatically at 1. 2 is a gas-engine connected with the producer by the gassupply pipe 3. The products of combustion from the gas-engine are shown having an exit through pipe 4:, which connects with the lower part of the cooler and reservoir 9. An outlet in this cooler is shown at 10, controlled by the damper 11. A jacket 13 surrounds cooler 9, allowing of. air-cooling by entrance of air at 15 and exit at 16. 5 is a passage connecting thecooler 9 with the producer 1. The valves or dampers 6, 8, 11, and 17 serve to adjust the flow of gas and secure the necessary' control and regulation of the apparatus.

In Fig. 2 the same apparatus is shown installed in the hull of a vessel. The same characters are used in this figure to distinguish certain of the parts that have been designated in Fig. 1. In addition connections are shown to shaft 20 and the screw 21. Piping 15 also is shown connecting with a ventilator on the deck of the vessel and terminating in the jacket 13. p

The operation of the apparatus is as follows: A deep bed of coalis brought to a state of ignition in the gas-producer 1, and the gas developed therefrom is passed through conduit 3 to the gas-engine 2, where air is admitted by any of the well-known methods to make the explosive mixture necessary to the operation of the engine. The products of combustion pass from the engine through pipe 4 to cooler 9, and a portion of these may be allowed to discharge through pipe 10. Another portion, well cooled, is drawn back to the producer through pipe 5. Air in so far as it may be needed is supplied at-7. Adjustment of the various gates or valves may be made until the producer is working at the proper temperature and delivering gas of a desirable quality. Increase in the amount of carbon dioxid is made by increasing the aperture of gate 5. Increase or decrease in the opening of gate 8 varies the air-supply. As the products of combustion tend to cool the fire, while the air acts as a vivifier, a mixture may be obtained by an adjustment of 6 and 8, which maintains the temperature of the producer at the most eifective and economical point and which prevents at the same time the formation of objectionable amounts of soot and clinker, which would interfere with the continuous operation of the apparatus. In Fig. 2 the air heated by the products of combustion is used for heating certain of the ships compartments.

What I claim isl. The combination of a gas-engine, aproducer for supplying gas for the operation of the engine, a gas-passage connecting the producer with the engine, means for returning a portion of the products of combustion to the producer, means for cooling said products of combustion, means for admitting air to said producer, and means for the adjustment of the relative proportion of products of combustion and air.

2. The combination of a gas-engine, a producer for supplying gas for the operation of the engine, a gas-passage connecting the gasproducer with the engine, a return-passage from the engine to the producer for supplying products of combustion to the producer, means-for cooling said products of combustion, and means for admitting air to form an endothermic gaseous mixture capable of regulating the temperature of the producer.

3. The combination of a gas-engine; a producer supplying gas for the operation of the engine; a passagefor delivering products of combustion from the engine to the gas-producer; in said passage an air-cooled heat-radiator through which the products of combustion pass and are positively cooled; and means for supplying to the gas-producer carbon dioxid and air in such amount as will control the temperature thereof.

4:. The combination of a gas-engine; a producer supplying gas for the operation of the engine; a gas-passage connecting the producer with the engine; means for returning a portion of the products of combustion to the producer; means for removing a portion of the sensible heat from said products of combustion prior to their entrance into said producer; and means for the adjustment of the relative proportion of the products of combustion and air.

5. The combination of agas-engine; a pro ducer for supplying gas for the operation of the engine; a gas-passage connecting the gasproducer with the engine; a return-passage from the engine to the producer for supplying products of combustion to the producer; means for positively cooling said products of combustion; and means for admitting air to form an endothermic gaseous mixture capable of regulating the temperature of the producer.

6. Combined power and power-gas apparatus comprising an internal-explosion engine; a gas-generator; a gas-conduit connecting said generator with said engine; a return-conduit from said engine to said generator whereby products of combustion are entered into said generator; in said return-conduit means for the removal from the products of combustion of a large proportion of their sensible heat; and means for mixing with said products of combustion a predetermined amount of air or oxygen to form an endothermic gaseous mixture capable of maintaining the producer at an effective gasifying temperature.
